Venus has a stronger greenhouse effect than Earth because the atmosphere of Venus consists of about 96.5% Carbon Dioxide (CO2), which is a greenhouse gas, and the planet itself has virtually no water. Earth's atmosphere, by comparison, only contains about 0.03% CO2 and is comprised of about 70% water.
Since Venus' atmosphere contains so much CO2, a vast majority of the infrared (heat) radiation that is radiated back upward from the surface after sunlight hits it, gets absorbed, redirected and essentially trapped within the atmosphere. As a result, temperatures within the atmosphere and on the surface rise to very high levels. Only when the temperature builds up so high, to about 730K (or 456.85°C), can heat finally begin to breakthrough and escape, thus leveling off the temperature.
It is this high temperature that has basically boiled almost all of the water from Venus' surface and which also helps to contribute to the already massive greenhouse effect because water helps to control atmospheric CO2 by absorbing it.

∙ 8y agoThe carbon dioxide has been sequestered from Earth's atmosphere. Most of it is either locked away in carbonate rocks such as limestone or has had the carbon turned into organic matter by living organisms. There are no oceans on Venus to produce carbonates nor is there life to capture carbon, so there has been no sequestration.

∙ 12y agoIt is not because Venusian atmospheric and surface temperatures are much lower than Earth's.

Is there more nitrogen or carbon dioxide in earth's atmosphere?
There is much more nitrogen in earth's atmosphere than carbon dioxide. Nitrogen forms about 79%, while carbon dioxide makes up about 0.04%.
What is the difference between the greenhouse effect on Venus and the greenhouse effect on Earth?
On Venus, the clouds are made of thick, dense carbon dioxide which traps the heat, tucking it in close to the Venutian surface.On Earth, greenhouse gases, carbon dioxide, methane and others act in much the same way, though not as intensely as on Venus.
Where on Earth has carbon been increasing in?
The carbon content of the Earth's atmosphere has been increasing, particularly in the form of carbon dioxide (CO2) but also in the form of methane (CH4) which will eventually burn and become more carbon dioxide. And, the carbon content of the ocean is also increasing since carbon dioxide has been dissolving in the ocean.
How does carbon dioxide form natural rainwater features?
its all to do with gravitational pull, basically rainwater holds carbon dioxide as it is fresh from the atmosphere then when it reaches earth there is more added to it because us humans and animals take in oxygen and breathe out carbon dioxide.
Formula for carbon dioxide?
The WORD EQUATION FOR CARBON DIOXIDE IS: CARBON + OXYGEN ---> CARBON DIOXIDE. ;)
Do venus and earth have the same amount of carbon dioxide?
No, Venus has far more carbon dioxide. Earth's atmosphere is about .04% carbon dioxide. By contrast, Venus has an atmosphere that is 96% carbon dioxide and 93 times thicker than earth's. This means that Venus' atmosphere contains over 200,000 times more CO2 than earth's atmosphere does.
What does Venus have more of than Earth?
Venus has a very thick atmosphere of Carbon dioxide. Its average surface pressure is a crushing 93 bar, or 93 times that of Earths.
What planet is dominated by carbon dioxide?
Venus and Mars both have atmospheres dominated by carbon dioxide. Both are composed of more than 90% carbon dioxide.
What is the major component of Venus's atmosphere?
The atmosphere of Venus consists mainly of carbon dioxide, and a small amount of nitrogen. The thick cloud cover is composed of sulfur dioxide and sulfuric acid droplets. Due to the dense atmosphere, the surface temperature ranges from 750 to 930 degrees Fahrenheit (398 to 498 Celsius). The surface pressure is 90 times that of Earth. That's like being one kilometer (more than half a mile) under the ocean.
Is the planet venus is made up of thick layer of sulphuric acid?
Venus's atmosphere is over 90% carbon dioxide and the atmospheric pressure at the surface is 93 times more than on Earth.
Is there more nitrogen or carbon dioxide in earth's atmosphere?
There is much more nitrogen in earth's atmosphere than carbon dioxide. Nitrogen forms about 79%, while carbon dioxide makes up about 0.04%.

What does carbon dioxide do to the Venus's atmosphere?
Just as the earth has naturally-occurring carbon dioxide in its atmosphere, so also does the planet Venus have naturally-occurring carbon dioxide in its atmosphere. Because the concentration of carbon dioxide is so high in the Venetian atmosphere, it has a more considerable greenhouse effect.
How is earth different to Venus's?
There are several differences between Earth and Venus. For one, Earth has water in all three states - gas, liquid, and solid - whereas Venus doesn't. Venus's thick, extensive cloud cover drops sulfur - filled acid rain on the landscape constantly. Lastly, Venus's atmosphere is about 98 times as dense as Earth's and contains much more carbon dioxide.
What is the atmoshperemade of in venus?
Mainly carbon dioxide (more than 96%), and a little bit of nitrogen.
What gas makes up most of the atmosphere of planet venus?
Venus is not made up of gas, but it does have a thick atmosphere. The main gas in the atmosphere is carbon dioxide, at about 96%. There's some nitrogen (about 3.5%) and traces of other things.
What planet has clouds and gravity like Earth?
Venus has a surface gravity slightly less than Earth's. It also has clouds, but not like Earth clouds -- Venus clouds are sulfuric acid, suspended in the dense, superheated carbon dioxide atmosphere. See the related link for more information.
